Information Technology deal with the use of electronic Computers and telecommunication equipments to convert, store, protect, process, transmit, and retrieve information.
The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones.
Information Technology Association of America, in a business context has defined information technology as "the study, design, development, application, implementation, support or management of computer-based information systems".
Several industries are associated with information technology, such as computer hardware, software, electronics,semiconductors, internet, telecom equipment, e-commerce and computer services. The responsibilities of those working in the field include network administration, software development and installation, and the planning and management of an organization's technology life cycle, by which hardware and software is maintained, upgraded, and replaced.
The term "information technology" in its modern sense first appeared in a 1958 article published in the Harvard Business Review; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Based on the storage and processing technologies employed, it is possible to distinguish four distinct phases of IT development: pre-mechanical (3000 BC – 1450 AD), mechanical (1450–1840), electromechanical (1840–1940) and electronic (1940–present).
The Term is used to describe the process involving recording, processing, storing, retrieving, transmitting, and again recording of information from the feedback.

E-Learning and Online community portals were very useful when it came to retrieving the required and relevant information.
